I am so happy that you decided to include the auto-fire QoL feature. I know that some players prefer to hammer the first button, but this made the game far more enjoyable for me personally - especially since the best strategy seems shoot constantly. I did need to mute the SFX, since the shooting "bloop" sound overlapped so aggressively with the music.
The art is extremely cute and charming. I love the wiggly 2-frame animations, and the thick lines in the spritework made the whole thing feel hand-drawn. This combined with the charming intro made this feel like a storybook.
The level of challenge was great! I was able to finish in my first attempt, but not without a few tense moments in the final waves.
I liked the variety of enemy types - although the shield guys did not feel wildly different, since my approach was the same - shoot 'em until they disappear! I did love the evasive charge of the skeletons, which was exciting the first time it happened. I think the shooting would feel way more satisfying if there was a slight knockback or slowdown on damaged enemies, but that is more my personal taste then a genuine critique.
This was a wonderful entry! I continue to be a big fan of yours, Achie!
